#to_sass ⇒ ::Sass::Tree::VariableNode, ::Sass::Tree::PropNode

Note:

Always put on a new line.

Converts this node to Sass::Tree::VariableNode, if it’s a variable definition. Otherwise it must be a CSS property declaration and gets converted to Sass::Tree::PropNode.

The 3rd param of ‘::Sass::Tree::PropNode` refers to the CSS syntax to be outputted. Its value can be:

- `:new` using `a: b`-style syntax
- `:old` using `:a b`-style syntax

For the sake of simplicity, we’ll use the new syntax only. Later could be set in cli arguments as option.
